可以定義實現監聽兩個微調和單選按鈕類,

創建類的一個實例,然後將該實例分配到兩個單選按鈕和微調。 例如:

package italialinux.example; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.AdapterView; 
import android.widget.AdapterView.OnItemSelectedListener; 
import android.widget.TextView; 


public class ButtonAction implements OnClickListener, OnItemSelectedListener { 

    TextView btnLocalText; 

    public ButtonAction(TextView tv) { 
     super(); 
     btnLocalText = tv; 
    } 

    @Override 
    public void onClick(View arg0) { 
     btnLocalText.setText("Hello from a ButtonAction!!"); 
    } 

    @Override 
    public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, 
      long arg3) { 
     // TODO Auto-generated method stub 

    } 

    @Override 
    public void onNothingSelected(AdapterView<?> arg0) { 
     // TODO Auto-generated method stub 

    } 

}

的問題是,我需要使用我在使用其他類的麻煩各種適配器。 – KRL

您在那裏添加的奇妙示例,謝謝。對於其他人來說,像我自己一樣,這是需要添加到你的按鈕/旋鈕/ misc來調用課程; clr.setOnClickListener(new ButtonAction('whatever value')); – KRL

如果你希望他們在點擊執行相同的功能,只需在setOnClickListener()方法中添加相同聽者實例每個視圖/小部件。如果沒有,那麼你將要檢測被單擊視圖和執行所需的操作相應

我想下面的代碼示例是你在尋找什麼

//the import for onClickListener you need is here (along with other imports --- you can get all of them by pressing ctrl+shift+o on Eclips IDE) 

進口android.view.View.OnClickListener;

公共類MyActivity擴展活動實現OnClickListener {

/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    Button myButton = (Button) findViewById(R.id.myButtonId); 
    ImageView myImageView = (ImageView) findViewById(R.id.myImageViewId); 
    RadioButton myRadioButton = (RadioButton) findViewById(R.id.myRadioButtonId); 
    CheckBox myCheckBox = (CheckBox) findViewById(R.id.myCheckBoxId); 

    myButton.setOnClickListener(this); 
    myImageView.setOnClickListener(this); 
    myRadioButton.setOnClickListener(this); 
    myCheckBox.setOnClickListener(this); 

} 

public void onClick(View view) { 

    switch (view.getId()) { 

    case R.id.myButtonId: 
     // do the work here for Button click listener 
     break; 

    case R.id.myImageViewId: 
     // do the work here for Image click listener 
     break; 

    case R.id.myRadioButtonId: 
     // do the work here for RadioButton click listener 
     break; 

    case R.id.myCheckBoxId: 
     // do the work here for CheckBox click listener 
     break; 

    } 

} 

}

不幸的是,它只是讓我的程序崩潰。感謝您的嘗試! – KRL
